BRAKE-ROD.

Specification of Letters Patent.

' Patented Jan. 22, 1907.

Application filed June 16, 1906. $erial11'0. 322,005.

To all whom it may concern: y

Be it known that I, LoUIs- A." HOEER, a citizen of the United States, residing at the city of St. Louis, State of Missouri, have invented a certain new and u'seful'Brake-Rod, of which the following is such a full, clear, and exact description as will enable any one skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to brake-rods, and more particularly to the lower rods of innerhung brakes, such rods when under load being compression members.

The object of my invention is to provide a rod which will have greater strength as a compression member than the ordinary solid brake-rod and which can be more easily secured to the brake-rod jaw without materially lessening its strength.

In the accompanying drawings, which illustrate a brake-rod made in accordance with my invention, Figure 1 is a view partly in plan and partly in section, the central portion of the rod being broken away; and Fig. 2 is a view similar to Fig. 1, but taken in adirection at right angles thereto.

Like marks of reference refer to similar parts in both views of the drawings.

5 represents the brake-rod proper, which in place of being a small solid rod, as heretofore, I make tubular and .of comparatively large diameter. Attached to each end of the rod 5 is a brake-rod jaw consisting of a shank 6 and a bifurcated end 7, adapted to receive a brake-lever.

In the drawings I have shown the brakerod jaw at the left-hand end provided witha single pair of openings 8 for the passage of the brake-j aw pin, while the jaw at the righthand end is provided with two such sets of openings. In each of the shanks 6 is formed a socket 9, adapted to receive one end of the rod 5, said socket being of such size that the rod fits snugly within it. The inner end 10 of each of the sockets 9 is arranged to bear against the end of the rod 5, and thus receive the thrust between the rod and the jaw when the rod is under load.

In order to prevent the accidental disengagement of the jaw from the rod, I provide pins 11, which pass through the shanks 6 of the jaws and through elongated openings 12 in the rod 5. These pins 11 may be secured in position in any suitable mannersuch, for instance, as by riveting thereon heads 13 as shown in the drawings.- The pins 11 are preferably two in number for each shank 6 and arranged at right angles to each other, as shown. The shanks 6 are preferably reinforced around the pins 11 by bosses 14.

The tubular rod 5 of comparatively large diameter has much more strength when used as a compression member than has the ordinary solld rod heretofore in use. As the openings 12 for the passage of the pins 11 are of comparatively small size in relation to the diameter of the tubular rod, these openings do not materially weaken the rod. Moreover, the rod at the point where it is pierced by the openings 12 is reinforced by the walls of the shank 6 of the jaw. The elongated form of the openings 12 insures the ends of the rod 5 seatingagainst the bearing-faces 10 of the shanks, so that when the rod is under load the entire loadis carried at this point, and there is consequently no tendency to shear the pins 11.

Having fully described my invention, what I claimas new, and desire to secure by Letters Patent of the United States, is

1. The combination with a tubular brakerod, of a jaw having a socket to receive saidrod-and bear againstthe end thereof, and fastening means for securing said jaw and rod together, said fastening means allowing,

relative movement between the rod and jaw.

2. The combination with a tubular brakerod, of a jaw having a socket to receive said rod and bear against the end thereof, and a pin passing through jaw and through elongated openings in said rod.

3. The combination with a tubular brakerod, of a jaw for each end of said rod, each of said jaws having a socket to receive said rod and bear against the end thereof, and pins passing through said jaws and through elongated openings in said rod.

In testimony whereof I have hereunto set my hand and afiixed my seal in the presence of the two subscribing witnesses.
